Analysis and comparison of several simple impulsive noise mitigation schemes for OFDM receivers (2008, background): “It is shown [14] that the optimal scaling factor, which satisfies E[dksk] = 0 can be found as”
M-QAM-OFDM system performance in the presence of a nonlinear amplifier and phase noise (2002, methodology): “More precisely, in [13], means and variances of the nonlinear distortion were obtained through simulations, while in [14] and [15] two different computational approaches were followed to derive an analytical expression for the autocorrelation function of the HPA-processed signal.”
A Review of Mutual Coupling in MIMO Systems (2018, background): “The latter can be regarded as an additional source of noise [82].”
Towards 10 Gb/s orthogonal frequency division multiplexing-based visible light communication using a GaN violet micro-LED (2017, methodology): “For Gaussian inputs such as the real-valued OFDM waveform, the Bussgang theorem can be applied and the nonlinear transformation can be expressed as [18]:”
Performance analysis of deliberately clipped OFDM signals (2002, background): “Based on this approach, the effects of nonlinearity of the high power amplifier (HPA) or ideally predistorted limiter on the OFDM signal have been analyzed in the recent literature, e.g., [14], [18]‐[ 22 ].”
